The wasp-mimicking hoverfly (Mesembrius sp.) is bright yellow in color with black stripes and can be found in Australia, India, England, and the UK. There are three conspicuous black markings on the thorax, and the abdomen is banded with black and yellow. In the 2nd segment, the black bands are connected by a median band. The wings are tinted with a pale brown. This fly is commonly found either resting on leaves or feeding on flowers. Its warning colors are effective at mimicking a wasp. It has short antennae and a single pair of wings, indicating it is a fly. Hoverflies have smaller antennae and larger eyes than wasps and bees, with their eyes appearing to wrap around their head. The wing-vein pattern helps to identify it as a hoverfly. This photo was taken in a forest at Tehatta, West Bengal, India, on 07/03/2024.
